This is something +3 and I are trying out and I think we will continue to do. In an effort to be less connected to our phones, we have decided to not bring our phones out when we go for walks or keep our phones in our bags when we have meals together.
It's a small gesture but really makes you realise how easily distracted one gets when the phone is within arms reach. This also allows us to pay full attention to each other and our surroundings. Hehe.
